To all 'whom it may concern:

Be it known that I, HENRY K. SHANCK, a citizen of thefUnited States, andresident of Cleveland, county` oi Cuyahoga, State of Ohio, have inventedcertain new and useful Improvements in. Gas-Generators orExplosion-Engines, of which I hereby declare the following to be a full,clear, and exact de# scription, such as will enable others skilled inthe art to which it appertains to make and use the same.

The objects of the invention are to providea quick running or two cycleengine in which .the exhaust containing the products of combustion shallbe practically odorless owing to the perfect degree of combustion of thegases obtained.

The objects are also to obtain increased power and eliciency in theengine by supplying a more intimately commingled mixture of gas and airto the explosion chamber under pressure.v This intimate mixture isproduced not by inspiration of air or injector action nor by means of acarbureter of the ordinary type, but the lluid is forced through anexceedingly minute opening with a ressure `of from 120 to 150 pounds,where y it becomes a mere mist or vapor so that the air surrounding thejet is immediately incorporated therewith and the mixture is combustibleto a degree unknown in dripping or sponge like 4carburete'rs where theexplosive oil is merely atomized or provided in minute drops. For thisreason a heavier and cheaper i'luid can be employed in an explosionengine, such as -a hydro-carbon or [luid rich in' carbonsu'ch as benzin,without danger of incomplete combustion Yand consequent depositl ofcarbon on the sparking contacts, or

disagreeable odor.

The invention consists in the elongated air and gas commingling chamberapplied to an especial -form 'of preliminary compression chamber asshown in my fori'ner ap lication No. .166,233 and inthe needle va vecontrolled inlet orilice for lluid, through which rojectedlongitudinally through the air and tne chamberin the form of a inist.

It also comprises .instrumentalities' for automatically forcing theVluid through the minute annular opening inthe valve 'at' a high degreeof pressure, since by extreme pressure only can the fluid be forcedthrough an opening thin enough to form the cloud or mist required forcomplete commingling with the air.

The invention also comprises instrumentalities for equalizing thepressure so as to make it continuous and instrumentalities for adjustingthe supply of iluid and air to the comminglinor chamber to respond tothe required speeil andV varying load upon the 'en'- me. g The inventionalso consists in the combination and arrangement of parts andconstruction o'f details as hereafter described, shown in theaccompanying drawings and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the device;Fig. 2 is a side elevation thereof; Fig. 3 is a vertical longitudinalsection through the commingling chamber and one of the twin cylinders'lof the engine and also through the condensing chamber for thatcylinder, and transverse passages leading to both coinmingling chambers;Fig. 4 is plan view ofthe outer portion of the commingling chambershowing the adjustment levers for the fluid and air valves Fig. 5 is anend view ol' the fluid inlet nozzle; Fig. 6 is a longitudinal section(enlarged) of the outer end of the commingling nozzle, showing needlevalve, and air inlet, also the valve or damper in the air inlet; Fig. 7is a vertical section showing the pump and valves by means of which theiluid is forced into the commingling chamber 5 Fig. 8 is a transversesection thereof and of a hand pump by which the initial pressure can beobtained before starting the engine; Fig. 9 is a plan view of the same.

The engine is shown as a multiple cylinder engine, having twoworkingcylindersl, 1, each of which is I rovided with a separate compressionchamber 3, which chambers are connected by a trunk or passage 4, whichconducts the charge to both of said chambers,

communication between the latter and said,l

chamber and fluid ment being such that the compression stroke of thepiston draws the charge from the trunk 4 into said chambers from whichit passes into the cylinders through the portsv 6, 6, when the pistonsuncover the same on their outward or working stroke.

The vcomminglin chamber is common to both cylinders in W ch the mixtureis alternately used, and comprises the tube 7 entering the transverseassage' 4, by means of a reduced inlet 8. n the outer end of this tubeor chamber is axially placed the nozzle 9 provided with the lateralinlet tube 10 for oil.V

The nozzle 9 is tapered at 11 where it enters the chamber, and a longneedle valve 12 controls a similarly tapered o eningin the nozzle. Thevalve stem is t eaded at 13 for minute adjustment and the valve isrovided with a shoulder 14 by means of whic all p ossible flow of oilcan be shut off from the commingling chamber. i

'l e long taperA of the needle makes together with the screw the finestadjustment ossible and the lever 15 upon the valve stem 1s designed torotate only througha part of a circle, since the desired opening is sominute as to require extreme pressure to drive the oil through.

.At one side of the chamber is the air inlet 16, controlled byfmeans 'ofthe rotaryvalve 17.

To enable the fluid inlet and'air controlling valves to operate inunison so that the requisite proportions ofair and gas shall bemamtained a governor 18 is employed to regulate their movements. Thisgovernor is operated by a sprocket or band Wheel 19 connected with asimilar Wheel 20 upon the engine shaft '21, by means of the band orchain 22,'and

pivoted to thegovernor rod 23 is seen a lever 24(pivoted at one end tothe engine bed-25 an at the other end to a link 26 which is connecteddirectly to the lever 15 operatingthe valve stem in the oil inletnozzle.

A rock arm 27 connects the lever 1'5 and a crank arm. 28 ofthe axial rodof a disk valve gine shaft, the oil is raised past the valve 34, whichprevents its return, and is forced past the spring pressed valve 35 andthrough the ipe 36 to an-air chamber 29 the air in which 1s compressedas the oil enters, and which maintalns the degree of pressure and alsoequalize it to produce vacontinuous flow.

Thence the oil passes throughthe pipe 37 to the commirigling chamber.

38 is the oil reservoir, 39 the pipe leading therefrom to the ump,v and40 is an overflow pipe leading ack to the reservoir and provided withthe valve 41, which contains a s ring and relieves excessive ressure.

he commingling chamberis s own to have a reduced extremity 8, and to liehorizontally in this manner providing a receptacle for overflow of oilin case a careless operator should leave the valve open fora long time,and in this manner the flooding of the engine will be prevented.

A hand pum 50 is used to obtain initial ressure-upon t e oil in the airchamber beore t e engine is started.
